When should a turn signal be activated before making a turn?

Activating a turn signal at least 100 feet away from the turn is crucial for ensuring safety and effective communication with other road users. This practice provides adequate warning to drivers behind you and those at intersections about your intention to turn. By signaling well in advance, you allow other vehicles and pedestrians time to react appropriately, helping to prevent accidents.

The requirement to signal well ahead of the turn is particularly important in maintaining flow and organization on the road. It enables other drivers to adjust their speed and position, ensuring that the turning vehicle does not disrupt the traffic movement. Using a signal only when you are close to the turn or in the intersection does not give others enough time to respond, which can lead to confusion or collisions.
